react-bootstrap: Modal not working

I am trying to get a modal to popup when Login is clicked but nothing populates.

Im using the ‘react-bootstrap’ library.

Here is the code:

var React  = require('react');
var Modal = require('react-bootstrap');

var Login = React.createClass({
  render: function() {
    return (
    <div className='static-modal'>
        <Modal title='Modal title'
          enforceFocus={false}
          backdrop={false}
          animation={false}
          container={mountNode}
          onRequestHide={function() {}}>
          <div className='modal-body'>
            One fine body...
          </div>
          <div className='modal-footer'>
            <Button>Close</Button>
            <Button bsStyle='primary'>Save changes</Button>
          </div>
        </Modal>
      </div>
    );
  }
});


module.exports = Login;

Any idea why it’s not rendering? What does MountNode have to be passed as?

FYI, I am also using react router to route thru the components.
